FIG. 1 is a flow chart of a network registration method of a mobile terminal according to an embodiment of the present disclosure. The network registration method is configured in a network registration apparatus of a mobile terminal for illustration. Embodiments of the present disclosure may be applied in a procedure when the user uses the mobile terminal to register 4G network, or may be applied in a procedure of registering 3G network or 2G network, which are not limited. The mobile terminal may be hardware devices with various operating systems, such as a smart phone, a tablet PC, a PDA, and an E-book.

The network registration method of the mobile terminal can include following actions in blocks illustrated in FIG. 1. The method can begin at block S11.

At block S11, an element T_(i) in a time array is read in response to determining that a predetermined abnormal event occurs when the mobile terminal registers a first network, in which the time array is {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, i is a positive integer between 1 and N, and N is a positive integer.

Embodiments of the present disclosure are illustrated in a case in which the mobile terminal registers the 4G network.

The execution body of embodiments of the present disclosure may be, for example, a built-in modem of the mobile terminal.

Alternatively, the predetermined abnormal event includes TAU being rejected.

The first network is 4G network.

It can be understood that, during the procedure in which the user uses the mobile terminal to access the 4G network, a response indicting a failure of registering the network may occur, in which the failure of registering the network may be caused by the TAU being rejected, or may be caused by other reasons.

In embodiments of the present disclosure, when the mobile terminal fails to register the network due to the TAU being rejected, the time array may be started and the element T_(i) in the time array may be read. For example, when the mobile terminal initially fails to register the first network, the element T₁ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and the mobile terminal is controlled to register the network with different rate, for example, 2G network or 3G network, during the time interval of T₁, to ensure that the mobile terminal can normally access to Internet. When the mobile fails to register the first network the second time, the element T₂ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and so on. The element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, to enhance the success rate of registering the first network by the mobile terminal, which is not limited.

A value of the element T_(i) in the time array may be set by the user based on his own demand, or may be preset by the manufacturer of the mobile terminal, which is not limited.

At S12, the mobile terminal is prohibited from registering the first network, and is controlled to register a second network.

In embodiments of the present disclosure, the second network has a transmission rate different from the first network. For example, the second network may be 2G network, or 3G network, which is not limited.

In embodiments of the present disclosure, when the mobile terminal initially fails to register the first network and when the mobile terminal fails to register the first network due to the TAU being rejected, it is possible to control the mobile terminal to switch to register the network with different rate, for example, 2G network or 3G network, in the time interval of T₁. Alternatively, when the mobile terminal alternately reads the element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, the mobile terminal may switch to register the network with different rate in the time interval of T_(i), thus effectively ensuring that the mobile terminal can normally access to Internet.

At S13, the timer is started to time, to obtain a first counted time.

In embodiments of the present disclosure, while the mobile terminal is prohibited from registering the first network and is controlled to register the second network, the timer may be started to time, to obtain the first counted time. The mobile terminal may determine whether the duration of registering the second network reaches T_(i) according to the first counted time, which is not limited.

At S14, it is determined whether the first counted time reaches T_(i).

In embodiments of the present disclosure, it is possible to determine whether the first counted time reaches T_(i), to determine whether to trigger the mobile terminal to re-register the first network, which is not limited.

In some embodiments, as illustrated in FIG. 2, following action may be performed after S14.

At S21, when the first counted time does not reach T₁, the mobile terminal is continuously controlled to register the second network.

In this action, by continuing to control the mobile terminal to register the second network when the first counted time does not reach T_(i), it can ensure that the user can register the network with different rate when the TAU is rejected by the network, avoiding the connectionless network service state, and effectively improving the user experience.

At S15, when the first counted time reaches T_(i), a first identity is obtained, in which the first identity is the TAI of an adjacent cell of a cell where the mobile terminal is when registering the first network.

In embodiments of the present disclosure, when the first counted time reached T_(i), the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network may be obtained, to control the mobile terminal to re-register the first network according to the TAI of the adjacent cell.

The TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network may be obtained by technologies in the related art, which will not be elaborated here.

At S16, the mobile terminal is controlled to re-register the first network according to the first identity.

In embodiments of the present disclosure, when the mobile terminal fails to register the first network the first time due to the TAU being rejected, the mobile terminal reads the element T₁ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}. In the time interval of T₁, the mobile terminal is prohibited from registering the first network, but switches to register the second network, and accesses to the second network in the time interval of T₁. Then, when the counted time of the times reaches T₁, the mobile terminal is controlled to re-register the first network according to the TAI of the adjacent cell. If the registration successes, the mobile terminal accesses to the first network. If the registration fails, the mobile terminal reads the element T₂ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} and resets the timer for timing again, and switches to register the second network again in the time interval of T₂. When the re-counted time reaches T₂, the mobile terminal is controlled to register the first network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network the second time. By that analogy, the element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, until the mobile terminal registers the first network successfully, which is not limited.

In this embodiment, by controlling the mobile terminal to register the second network when the predetermined abnormal event occurs during the mobile terminal registers the first network, it can ensure that the user registers the network successfully, and by obtaining the first identity (the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network) when the first counted time reaches T_(i), and controlling the mobile terminal to re-register the first network according to the first identity, the mobile terminal can register the network of the cell with different TAI when the current TAU is rejected by the network, thus effectively enhancing the success rate of registering the network.

FIG. 3 is a flow chart of a network registration method of a mobile terminal according to an embodiment of the present disclosure. The network registration method is configured in the network registration apparatus of the mobile terminal for illustration.

The network registration method of the mobile terminal includes following actions in blocks illustrated in FIG. 3. The method can begin at block S301.

At S301, the value of the element T_(i) in the time array is set according to a user command.

In this embodiment, the value of the element T_(i) in the time array may be preset by the user based on this own demand.

For example, the mobile terminal may receive the command input by the user on the screen, and sets the value of the element T_(i) in the time array according to the user command. The values of the elements T_(i) in the time array may be sequentially input by the user on the screen, or may be selectively input by the user, which is not limited.

In this action, the time T_(i) of the time array is set by the user, and thus personalized setting of the time array may be realized, the generality of the network registration method of the mobile terminal may be improved, and the success rate of the network registration of the mobile terminal may be enhanced.

At S302, it is determined whether the predetermined abnormal event occurs when the mobile terminal registers the first network, and if yes, S303 is executed, and if no, S315 is executed.

The execution body of embodiments of the present disclosure may be, for example, a built-in modem of the mobile terminal.

Alternatively, the predetermined abnormal event includes TAU being rejected.

The first network is 4G network.

It can be understood that, during the procedure in which the user uses the mobile terminal to access the 4G network, a response indicting a failure of registering the network may occur, in which the failure of registering the network may be caused by the TAU being rejected, or may be caused by other reasons. This embodiment is applied in the procedure in which the mobile terminal registers the network, and is applied after the TAU is rejected.

Alternatively, it is possible to determine whether the event of the TAU being rejected by the network occurs during the mobile terminal registers the 4G network, to trigger subsequent actions.

At S303, the element T_(i) in the time array is read, in which the time array is {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, i is a positive integer between 1 and N, and N is a positive integer.

In embodiments of the present disclosure, when the mobile terminal fails to register the network due to the TAU being rejected, the time array may be started and the element T_(i) in the time array may be read. For example, when the mobile terminal initially fails to register the first network, the element T₁ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and the mobile terminal is controlled to register the networks with different rate, for example, 2G network or 3G network, during the time interval of T₁, to ensure that the mobile terminal can normally access to Internet. When the mobile fails to register the first network the second time, the element T₂ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and so on. The element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, to enhance the success rate of registering the first network by the mobile terminal, which is not limited.

The value of the element T_(i) in the time array may be set by the user based on his own demand, or may be preset by the manufacturer of the mobile terminal, which is not limited.

At S304, the mobile terminal is prohibited from registering the first network, and is controlled to register the second network.

In embodiments of the present disclosure, the second network has a transmission rate different from the first network. For example, the second network may be 2G network, or 3G network, which is not limited.

In embodiments of the present disclosure, when the mobile terminal initially fails to register the first network and when the mobile terminal fails to register the first network due to the TAU being rejected, it is possible to control the mobile terminal to switch to register the network with different rate, for example, 2G network or 3G network, in the time interval of T₁. Alternatively, when the mobile terminal alternately reads the element T_(i) in the time array {T₁, T₂, T_(i), T_(i+1), . . . , T_(n)}, the mobile terminal may switch to register the network with different rate in the time interval of T_(i), thus effectively ensuring that the mobile terminal can normally access to Internet.

At S305, the timer is started to time, to obtain the first counted time.

In embodiments of the present disclosure, while the mobile terminal is prohibited from registering the first network and is controlled to register the second network, the timer may be started to time, to obtain the first counted time. The mobile terminal may determine whether the duration of registering the second network reaches T_(i) according to the first counted time, which is not limited.

At S306, it is determined whether the first counted time reaches T_(i), and if yes, S308 is executed, and if no, S307 is executed.

In embodiments of the present disclosure, it is possible to determine whether the first counted time reaches T_(i), to determine whether to trigger the mobile terminal to re-register the first network, which is not limited.

At S307, the mobile terminal is continuously controlled to register the second network.

In this action, by continuing to control the mobile terminal to register the second network when the first counted time does not reach T_(i), it can ensure that the user can register the network with different rate when the TAU is rejected by the network, avoiding the connectionless network service state, and effectively improving the user experience.

At S308, the first identity is obtained, in which the first identity is the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network.

In embodiments of the present disclosure, when the first counted time reaches T_(i), the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network may be obtained, to control the mobile terminal to re-register the first network according to the TAI of the adjacent cell.

The TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network may be obtained by technologies in the related art, which will not be elaborated here.

At S309, the mobile terminal is controlled to re-register the first network according to the first identity.

In embodiments of the present disclosure, when the mobile terminal fails to register the first network the first time due to the TAU being rejected, the mobile terminal reads the element T₁ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}. In the time interval of T₁, the mobile terminal is prohibited from registering the first network, but switches to register the second network, and accesses to the second network in the time interval of T₁. Then, when the counted time of the timer reaches T₁, the mobile terminal is controlled to re-register the first network according to the TAI of the adjacent cell. If the registration successes, the mobile terminal accesses to the first network. If the registration fails, the mobile terminal reads the element T₂ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} and resets the timer for timing again, and switches to register the second network again in the time interval of T₂. When the re-counted time reaches T₂, the mobile terminal is controlled to register the first network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network the second time. By that analogy, the element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, until the mobile terminal registers the first network successfully, which is not limited.

At S310, it is determined whether the predetermined abnormal event occurs when the mobile terminal re-registers the first network, and if yes, S311 is executed, and if no, S315 is executed.

It can be understood that, during the procedure in which the user uses the mobile terminal to access the 4G network, a response indicting a failure of registering the network may occur, in which the failure of registering the network may be caused by the TAU being rejected, or may be caused by other reasons.

Alternatively, it is determined whether the TAU is rejected by the network when the mobile terminal re-registers the first network, to trigger subsequent actions.

At S311, the mobile terminal is controlled to re-register the second network, and the timer is reset to time again to obtain the second counted time.

In embodiments of the present disclosure, when the mobile terminal fails to re-register the first network and when the mobile terminal fails to register the first network due to the TAU being rejected, it is possible to control the mobile terminal to switch to register the network with different rate, for example, 2G network or 3G network, in the time interval of T₂. Alternatively, when the mobile terminal alternately reads the element T_(i+1) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, the mobile terminal may switch to register the network with different rate in the time interval of T_(i+1), thus effectively ensuring that the mobile terminal can normally access to Internet.

While the mobile terminal is prohibited from registering the first network and is controlled to register the second network, the timer may be started to time, to obtain the second counted time. The mobile terminal may determine whether the duration of registering the second network reaches T_(i+1) according to the second counted time, which is not limited.

At S312, it is determined whether the second counted time reaches T_(i+1).

In embodiments of the present disclosure, it is possible to determine whether the second counted time reaches T_(i+1), to determine whether to trigger the mobile terminal to re-register the first network, which is not limited.

At S313, when the second counted time reaches T_(i+1), the second identity is obtained, in which the second identity is the TAI of the adjacent cell of the cell where the mobile terminal is when re-registering the first network.

In embodiments of the present disclosure, when the second counted time reaches T_(i+1), the TAI of the adjacent cell of the cell where the mobile terminal is when re-registering the first network may be obtained, to control the mobile terminal to re-register the first network according to the TAI of the adjacent cell.

The TAI of the adjacent cell of the cell where the mobile terminal is when re-registering the first network may be obtained by technologies in the related art, which will not be elaborated here.

At S314, the mobile terminal is controlled to re-register the first network according to the second identity.

In embodiments of the present disclosure, when the mobile terminal fails to re-register the first network due to the TAU being rejected, the mobile terminal reads the element T₂ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}. In the time interval of T₂, the mobile terminal is prohibited from registering the first network, but switches to register the second network, and accesses to the second network in the time interval of T₂. Then, when the counted time of the timer reaches T₂, the mobile terminal is controlled to re-register the first network according to the TAI of the adjacent cell. If the registration successes, the mobile terminal accesses to the first network. If the registration fails, the mobile terminal reads the element T₃ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} and resets the timer for timing again, and switches to register the second network again in the time interval of T₃. When the re-counted time reaches T₃, the mobile terminal is controlled to register the first network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network the second time. By that analogy, the element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, until the mobile terminal registers the first network successfully, which is not limited.

At S315, information about the TAU being rejected is obtained and sent to the server, such that the server backs up the predetermined abnormal event according to the information.

Alternatively, the mobile terminal obtains the information about the TAU being rejected by the network, and sends the information to the server, such that the server backs up the predetermined abnormal event according to the information.

In this embodiment, the time T_(i) of the time array is set by the user, and thus personalized setting of the time array can be realized, and generality of the network registration method of the mobile terminal can be improved. By controlling the mobile terminal to register the second network when the predetermined abnormal event occurs during the mobile terminal registers the first network, it can ensure that the user registers the network successfully, and by obtaining the first identity (the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network) when the first counted time reaches T_(i), obtaining the second identity (the TAI of the adjacent cell of the cell where the mobile terminal is when re-registering the first network) when the second counted time reaches T_(i+1), and controlling the mobile terminal to re-register the first network according to the first identity or the second identity, the mobile terminal can register the network of the cell with different TAI when the current TAU is rejected by the network, thus effectively enhancing the success rate of registering the network.

In order to illustrate the actions of the above embodiments more clearly, an example is given as follows.

As an example, when the time array is {1 min, 6 min, 12 min}, it indicates that the mobile terminal reads the element 1 min in the time array {1 min, 6 min, 12 min} when the mobile terminal fails to register the 4G network the first time due to the TAU being rejected. In the time interval of 1 min, the mobile terminal is prohibited from registering the first network, and switches to register the 2G or 3G network. The mobile terminal accesses to the 2G or 3G network in the time interval of 1 min. then, when the counted time of the timer reaches 1 min, the mobile terminal is controlled to re-register the 4G network according to the TAI of the adjacent cell. If the registration successes, the mobile terminal accesses to the 4G network. If the registration fails, the mobile terminal reads the element 6 min in the time array {1 min, 6 min, 12 min}, and re-starts the timer for timing. In the time interval of 6 min, the mobile terminal switches to register the 2G or 3G network again. When the re-counted time reaches 6 min, the mobile terminal is controlled to register the 4G network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the 4G network the second time. If the registration successes, the mobile terminal accesses to the 4G network. If the registration fails, the mobile terminal reads the last element 12 min in the time array {1 min, 6 min, 12 min} and re-starts the timer for timing. In the time interval of 12 min, the mobile terminal switches to register the 2G or 3G network again. When the re-counted time reaches 12 min, the mobile terminal is controlled to register the 4G network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the 4G network the third time. By that analogy, the mobile terminal then re-searches for the 4G network every 12 min. In this way, it can ensure that the user can register the network with other rate when the TAU is rejected by the network, avoiding the connectionless network service state.

The execution body of embodiments of the present disclosure may be, for example, a built-in modem of the mobile terminal.

Alternatively, the predetermined abnormal event includes TAU being rejected.

The first network is 4G network.

It can be understood that, during the procedure in which the user uses the mobile terminal to access the 4G network, a response indicting a failure of registering the network may occur, in which the failure of registering the network may be caused by the TAU being rejected, or may be caused by other reasons.

In embodiments of the present disclosure, when the mobile terminal fails to register the network due to the TAU being rejected, the time array may be started and the element T_(i) in the time array may be read. For example, when the mobile terminal initially fails to register the first network, the element T₁ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and the mobile terminal is controlled to register the network with different rate, for example, 2G network or 3G network, during the time interval of T₁, to ensure that the mobile terminal can normally access to Internet. When the mobile fails to register the first network the second time, the element T₂ may be read from the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)}, and so on. The element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, to enhance the success rate of registering the first network by the mobile terminal, which is not limited.

A value of the element T_(i) in the time array may be set by the user based on his own demand, or may be preset by the manufacturer of the mobile terminal, which is not limited.

At S12′, the mobile terminal is prohibited from registering the first network, and is controlled to register a second network.

In the time interval of T₁, the mobile terminal is prohibited from registering the first network, but switches to register the second network, and accesses to the second network in the time interval of T₁. Then, when the counted time of the times reaches T₁, the mobile terminal is controlled to re-register the first network according to the TAI of the adjacent cell. If the registration successes, the mobile terminal accesses to the first network. If the registration fails, the mobile terminal reads the element T₂ in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} and resets the timer for timing again, and switches to register the second network again in the time interval of T₂. When the re-counted time reaches T₂, the mobile terminal is controlled to register the first network again according to the TAI of the adjacent cell of the cell where the mobile terminal is when registering the first network the second time. By that analogy, the element T_(i) in the time array {T₁, T₂, . . . , T_(i), T_(i+1), . . . , T_(n)} is read alternately, until the mobile terminal registers the first network successfully, which is not limited.
